Water Chestnut Planting Methods: Key Points of Cultivation and Water Management Techniques

Water chestnut is a plant native to China, and it is now distributed in most parts of the world. Its planting area is mainly concentrated in the tropical provinces of China. It can be eaten not only as a fruit but also stir-fried, and it also has certain medicinal effects, as it can promote gastrointestinal peristalsis. So how should we manage water chestnut when planting it? Below, the editor brings you the key points of field management for water chestnut. Let's take a look!

1. Management during the seedling stage

The period from when water chestnut seeds germinate until before they tiller is its seedling stage, and water chestnut lives in water. Therefore, during its seedling stage, the water level should be kept at about 4 cm. About half a month after transplanting, water chestnut enters the tillering stage. During this period, pay attention to observing the growth of the seedlings. Weeds and yellow stems and other substances that affect stem growth should be removed in time, and they can be buried in the field, which can promote the growth of the planted water chestnut. Then apply a topdressing of nitrogen fertilizer once, and control the amount well to prevent excessive use from causing fertilizer damage to water chestnut.

2. Management during the nutritional stage

When water chestnut enters the tillering stage, focus on doing a good job of weeding, and try to carry out each weeding together with topdressing as much as possible. The main fertilizer is also nitrogen fertilizer. During the vigorous growth period of the corms, pay attention to raising the water level. Raise the water level to about 7-8 cm, and during the nutritional stage, the damage caused by pests and diseases to water chestnut is relatively serious. For example, dry rot and stem borers, so we should also take corresponding control measures according to the pests and diseases, enhance the growth ability of water chestnut, increase yield, and protect our own planting benefits.

3. Field management

After water chestnut is transplanted and planted, the soil temperature should be appropriately raised to promote the revival and tillering of water chestnut seedlings, and water should be applied appropriately. Then, as the seedlings grow, the field's water consumption will gradually increase, so we should appropriately raise the water level according to the actual situation. Promote the growth of the aboveground part. Then after the rows close, control the application of nitrogen fertilizer, because if there is too much nitrogen fertilizer, it is very easy to cause excessive vegetative growth of water chestnut seedlings. During the period from sowing to harvesting of water chestnut, water shortage must not occur, especially during the enlargement period, because if there is a water shortage, it will have a great impact on yield.

4. Pest and disease control

The damage caused by pests and diseases to water chestnut is very serious, so pest and disease control is also a management task we need to focus on doing well. Common pests and diseases of water chestnut include fusarium wilt, sclerotinia, and locusts. Therefore, we should strengthen management, water and fertilize reasonably, and while meeting the water and fertilizer needs of water chestnut, we should also avoid waterlogging and fertilizer damage, and increase the incidence of pests and diseases. We should understand the symptoms of each pest and disease so that after onset we can promptly identify the specific pest or disease and take corresponding control measures.

The above is a brief introduction to the key points of field management for water chestnut. The management work for water chestnut is very important, so we must attach importance to it when planting to protect our own planting benefits. That is all for today's introduction.
